New York AGRICULTURAL EXPERIMENT STATION. 725 
infrequently found on pumpkin and squash vines as well. The 
insect itself is frequently spoken of, in common with the plant 
hice in general, as the “ green fly.” Strictly speaking, however; 
it is not a fly at all, but a true bug, belonging to the same order 
as the squash.bug.- Fig. 2 represents a winged viviparous female. 
These insects obtain their food in the same manner as the 
squash bug, that is, by puncturing the tissue and sucking the 
sap from beneath. As they are very small, it would at first seem 
that their work would not be sufficient to seriously injure the 
plant. This would be true were it not for the rapidity with 
which they reproduce. A single female will soon have a great 
number of offspring around her, and these; in turn, will very 
quickly reproduce, until an immense colony or number of colo- 
nies are formed. These little insects seem never to satisfy their 
hunger, but when gorged eject a drop of clear honey-dew from 
the anal opening and are again ready to renew the attack. Thus 
the plant suffers from thousands of minute punctures through 
which the sap is almost constantly flowing. A black fungus 
grows in this honey-dew, giving the leaves where the insects 
have congregated a blackened, unsightly appearance. 
Remedies. 
No suggestions as to remedies, based on field experiments, can 
be made at this time, as the work here was begun so late in the 
_ season that the insects had disappeared. It is desired that the 
appearance or suspected appearance of this insect on any part of 
the island will be reported at once to the entomologists of the 
Station. On badly affected vines a spray of kerosene emulsion, tf 
thoroughly applied, will prove effective in dislodging and destroy- 
ing the lice. The emulsion may be used at the rate of one part 
of the emulsion to from 12 to 15 parts of water. Owing to the 
curling of the leaves it is not an easy matter to reach the lice 
with a spray, and hence much pains should be taken to do the 
-work thoroughly. A knapsack sprayer has been found very con- 
yenient for such work as this. The sprayer referred to is manu” 
factured by W. & B. Douglas, of Middletown, Conn., and cost 
$10. Itis made of copper throughout, and is provided with an 
underspray nozzle by means of which the spray is directed to the 
underside of the leaf. Cheaper sprayers of a similar nature are 
on the market however. Whale oil soap is also recommended
